Assuming this text is in a file named mydata.txt and you want to read it into MATLAB, you can use TEXTSCAN. In the data, I see each row appears to have 5 numbers followed by a date and a time. In the format specifier then, I'd use %f to capture the numbers and %s for the dates and times. TEXTSCAN also allows you to define the delimiter:
fid = fopen('mydata.txt');
data = textscan(fid,'%f%f%f%f%f%s%s','Delimiter',',');
fclose(fid)
The "data" variable is now a cell array, with a cell for each column:
>> data{1}
ans =
39.9847
39.9847
39.9847
39.9847
39.9847
